Abstract
An atrial shunt regulation device, a braid tool and a braid method thereof. The left disk () and the right disk () of the atrial shunt regulation device are connected via the intermediate portion () as a single piece, and the left disk (), the intermediate portion () and the right disk () are braided by a single braid wire (). The ends of the braid wires are secured by one nut in the single-braid method, which reduces the number and size of the nuts and easily forms a cortical layer. The braid tool for braiding an atrial shunt regulation device comprises a cylinder braid body mold (), the cylindrical braid body mold () includes positioning pins () that are evenly connected to an outer wall of the braid body mold. The braid method of the atrial shunt regulation device comprises braiding, thermoforming, braiding a binding-off wire, securing ends of wires by a nut, and thermoforming again. The braid method is easy, the process is easy, and the device can be made manually in small batches to reduce costs.
